RICHMOND — A teenage boy who was one of two shooting victims outside a Target store on Tuesday was in stable condition early Wednesday morning and expected to survive his injuries, police said.

Investigators were still gathering clues Wednesday morning to determined what may have caused the shooting, which happened around 5:43 p.m. outside the Target store in the middle of an outdoor shopping center on Macdonald Avenue near 42nd Street, Richmond police Sgt. Nicole Abetkov said.

A 17-year-old boy who was critically wounded was airlifted to John Muir Medical Center in Walnut Creek, underwent emergency surgery and was stabilized by Wednesday, Abetkov said. The second male victim, whose age was not available immediately, suffered a gunshot wound that wasn’t considered life-threatening and was treated and released from Doctors Medical Center in San Pablo on Tuesday night, she said.

Police received multiple 911 calls from people near the scene, and members of the department, including police Chief Chris Magnus also were in the area and reported it.

In a Twitter post Wednesday, Magnus said the shootings is reminder that “violence reduction efforts are our #1 priority.”

Detectives say the shooting was not a drive-by and that a disagreement may have occurred between the shooter and the victims, Abetkov said. The victims knew one another and were patrons of the store. Police did not say whether the victims knew the shooter.

“This happened right in the middle of the shopping center, so there were a lot of people there,” Abetkov said. “So we’re hoping to talk to them, and our guys are going from store to store hoping that there’s surveillance tape that might tell us more.”

Police did not have information regarding a suspect but did say that both the suspect and victims were gone form the area when officers arrived. Doctors Medical Center later notified Richmond police that two male victims had arrived with gunshot wounds.

Anyone with information or who may have seen the shooting is urged to call Richmond police at 510-232-1214. Anonymous tips can be left at 510-232-TIPS.
